A cold low-pressure system from the north is expected to bring much cooler weather starting Saturday, with a good chance of showers and possible snow in the mountains, forecasters said Tuesday.
The National Weather Service office in San Diego said rain could be locally heavy and continue through Tuesday. Thunderstorms, hail and, above 5,500 feet, snow are also possible.
“The big change will be Saturday when a closed upper low approaches from the north and brings much cooler weather,” the weather service said.
Temperatures along the coast will drop into the mid 60s during the day and to the low 50s at night.
The weather service said up to an inch of rain is possible in some area and there is also a chance of lightning.
